The Microservices - Database per Service design pattern advocates for each microservice to have its own private database. This design pattern is crucial for achieving loose coupling between microservices, allowing each service to be developed, deployed, and scaled independently. Here are the main elements of this pattern:
Service Independence: Each microservice has its own database schema and database server. This isolation ensures that services do not interfere with each other’s data.
Scalability: Individual microservices can be scaled independently according to their specific data access and storage needs.
Polyglot Persistence: Different microservices can use different types of databases (SQL, NoSQL, etc.) based on their specific requirements.
Data Consistency: Ensuring eventual consistency through patterns like Saga or event sourcing is crucial since distributed transactions are not feasible.
Security and Access Control: Each microservice manages its own database security, ensuring data encapsulation and reducing the risk of unauthorized access.
